野生动物学报东北虎（Panthera tigris altaica）是体型最大的猫科（Felidae）动物之一，是极具代表性的珍稀野生动物。现有研究表明，我国野生东北虎种群遗传多样性较低、近交水平较高。尽管目前我国野生东北虎的数量在逐步增长，但通过人工干预来提高野生东北虎的遗传多样性会更利于其数量的恢复，通过野化放归进行遗传拯救是一种关键策略，但实施遗传拯救之前，必须确定圈养个体与现存野生个体间的遗传关系。采用粪便DNA的高通量测序数据组装了51只横道河子圈养东北虎和13只完达山 ...

野生动物学报, 2017 根据1971～2013年北京动物园圈养平原斑马的数据,应用种群管理软件SPARKS v1.6和PMx v1.0对北京动物园斑马圈养种群进行数据整理、统计学和遗传学分析。结果显示该种群数量呈现稳定缓慢增长的状态。目前,北京动物园斑马种群面临的问题主要为性别比例偏离了斑马固有的一雄多雌的种群结构,雄性个体较多; 基因多样性丢失较快。奠基者的后代数明显不均衡,导致现今基因多样性下降至83%,并存在大量半同胞间的近亲繁殖,且现有可配对个体严重不足。1岁前是幼龄斑马的死亡高峰期,流产、死胎为死亡主要原因 ...

野生动物学报, 2020 黄颊长臂猿属于IUCN濒危物种，仅分布于老挝、越南和柬埔寨。该物种微卫星的研究尚未报道。本研究，对黄颊长臂猿SSR位点进行筛选，并对南京地区圈养黄颊长臂猿种群进行了遗传多样性分析，统计了等位基因数、有效等位基因数，计算了群体杂合度、多态信息含量（PIC）、亲缘系数等参数。结果显示，共获得黄颊长臂猿11个多态性微卫星位点，等位基因数在2—5之间，多态信息含量为0.175—0.701，观测杂合度（Ho）为0.067—0.8，期望杂合度（He）为0.191—0.770，其个体间亲缘系数普遍偏高 ...

野生动物学报, 2020 濒危物种绿孔雀目前仅分布于中国云南省。2015—2018年，采用信访和野外调查对云南中部、南部和西部的绿孔雀种群现状和分布进行了调查。野外调查包括样线法、样点法和访问调查。结果表明，中国现存野生绿孔雀种群数量较20多年前800—1 100只大幅度减少，约为235—280只。在云南的分布范围较1995年的32个县缩减至13个县。绿孔雀栖息环境主要是热带、亚热带常绿阔叶林和林型较为开阔的低密度思茅松林。由于栖息地碎片化严重，绿孔雀现存种群呈小家族群点状隔离分布 ...

Conservation Biology, Volume 37, Issue 2, April 2023., 2023 Abstract Managed breeding programs are an important tool in marsupial conservation efforts but may be costly and have adverse genetic effects in unavoidably small captive colonies. Biobanking and assisted reproductive technologies (ARTs) could help overcome these challenges, but further demonstration of their potential is required to improve uptake. We

Bibliometric investigation of the integration of animal personality in conservation contexts
Conservation Biology, Volume 37, Issue 2, April 2023., 2023 Abstract Consistent individual differences in behavior, commonly termed animal personality, are a widespread phenomenon across taxa that have important consequences for fitness, natural selection, and trophic interactions. Animal personality research may prove useful in several conservation contexts, but which contexts remains to be determined.

Conservation Biology, Volume 37, Issue 1, February 2023., 2023 Abstract Advancements in the field of reintroduction biology are needed, but understanding of how to effectively conduct translocations, particularly with snakes, is lacking. We conducted a systematic review of snake translocation studies to identify potential tactics for reducing postrelease effects. We included studies on intentional, human‐mediated,

Importance of health assessments for conservation in noncaptive wildlife
Conservation Biology, Volume 36, Issue 1, February 2022., 2022 Abstract Wildlife health assessments help identify populations at risk of starvation, disease, and decline from anthropogenic impacts on natural habitats. We conducted an overview of available health assessment studies in noncaptive vertebrates and devised a framework to strategically integrate health assessments in population monitoring.

Applying the zoo model to conservation of threatened exceptional plant species
Conservation Biology, Volume 34, Issue 6, Page 1416-1425, December 2020., 2020 Abstract Maintaining a living plant collection is the most common method of ex situ conservation for plant species that cannot be seed banked (i.e., exceptional species). Viability of living collections, and their value for future conservation efforts, can be limited without coordinated efforts to track and manage individuals across institutions. Using
